Trait backtalk::Adapter [−] [src]

pub trait Adapter: Send + Sync {
    fn list(
        &self, 
        params: &JsonObject
    ) -> BoxFuture<JsonObject, (ErrorKind, JsonValue)>;
    fn get(
        &self, 
        id: &str, 
        params: &JsonObject
    ) -> BoxFuture<JsonObject, (ErrorKind, JsonValue)>;
    fn post(
        &self, 
        data: &JsonObject, 
        params: &JsonObject
    ) -> BoxFuture<JsonObject, (ErrorKind, JsonValue)>;
    fn patch(
        &self, 
        id: &str, 
        data: &JsonObject, 
        params: &JsonObject
    ) -> BoxFuture<JsonObject, (ErrorKind, JsonValue)>;
    fn delete(
        &self, 
        id: &str, 
        params: &JsonObject
    ) -> BoxFuture<JsonObject, (ErrorKind, JsonValue)>;

    fn handle(&self, req: Request) -> BoxFuture<Reply, Error> { ... }
}

Converts a Request to a static Reply from a database.

An Adapter talks to a database. If you're using an Adapter, and not implementing your own, you probably just want to use the handle function. By implementing the five functions list, get, post, patch and delete, an Adapter gets the handle function for free.

You most likely won't want to implement your own Adapter, since these are generic and don't contain project-specific code. Backtalk implements memory::MemoryAdapter for development, but you will hopefully eventually be able to find third-party adapters for various databases in other crates.

Required Methods

Provided Methods

Takes a Request, passes it to the appropriate function, and turns the response into a proper Reply future. If you're using an Adapter in your webapp, this is the function you want to call.
